Azure - Hypervisor Generation 2 VMs (e.g. ARM based machines) are failing to create VM

[toschneck]

What happened?

If a Machine Deployment with some Azure Hypervisior Gen 2 Types got selected (in my case a ARM based Standard_D2ps_v5 ), KKP fails to provision with the error:

failed to create machine at cloudprovider, due to trying to create a VM: compute.VirtualMachinesClient#CreateOrUpdate: Failure sending request: StatusCode=400 -- Original Error: Code="BadRequest" Message="The selected VM size 'Standard_D2ps_v5' cannot boot Hypervisor Generation '1'. If this was a Create operation please check that the Hypervisor Generation of the Image matches the Hypervisor Generation of the selected VM Size. If this was an Update operation please select a Hypervisor Generation '1' VM Size. For more information, see https://aka.ms/azuregen2vm"

Unfortunately right now all ARM machines are only supporting Gen 2 Hypervisors, so basically we can't provision right now ARM based machines in KKP :-/

KKP 2.25.0

KKP 2.24.2

Expected behavior

Also Arzue generation 2 VM sizes get provisioned, as we also Display them to select.

How to reproduce the issue?

Create a new Azure Cluster (or add a Machine Deployment) and select an Gen 2 Machine Type, e.g. Standard_D2ps_v5.

How is your environment configured?

• KKP version: 2.25.0 and 2.24.2 are not working (I would assume that all versions are effected)
• Shared or separate master/seed clusters?: shared
